    HS2 with Coolrunner II

    Hi @Imjustatech, I apologize for the delay. Since the chip your customer is using seems to be a Xilinx automotive chip, those particular map files are not loaded into Adept, so Adept is not able to recognize it and properly program it on it's own unfortunately. You would either need ISE installed or your own custom application in order to program that chip, however from what I recall, the ISE that Xilinx released for Windows 10 only supports Spartan 6 devices, so I do not think it will readily work in that case. Thank you, JColvin

    ZYNQ -7020 Development Board OOB code

    Hi @ArKay99, I ran the project as is from the downloaded file as on Vivado 2016.4 and it generated with no errors and everything looks as it should. I was also able to have it generate a bitstream successfully as well and launch on SDK as well. What commands did you use to create the project? In the readme there is a small typo when running the create_project script. I don't know if you corrected it already but the correct formatting is as follows (modified for the path of where I stored my project when I ran it for the Zybo Z7-20): cd C:/Users/jcolvin/Documents/VivadoPrj/zybo_z7_bist/z20/demo/proj/ source ./create_project.tcl Did you do the same for your project? I'm guessing that you have the Zybo Z7-20 board based on your previous thread, though I don't know that for certain. As for reading a bitstream from an FPGA after it's programmed onto it, those of us at Digilent haven't done that, but there are a few threads about it here, here, and here. Thanks, JColvin

    PmodISNS20, Minimum Measurable Current

    Hi @syu, I was checking at the same time as @jpeyron, but it looks like the resolution of the Pmod ISNS20 current sensing chip (link to manufacturers website for the ACS722) is 66 mV/A. So, if you were wanting to measure with a 0.1 mA resolution, that would equate to about 6.6 uV detection capabilities, which between the sensitive error of the current sensor and the resolution of the attached ADC (0.732 mV per LSB), the Pmod ISNS20 will not meet your needed capabilities. Thanks, JColvin

    ethernet ps lwip and intc does not work

    Hi @rahulgujaran, Which Zynq hardware are you using? A Zybo, Zybo Z7-10 or Zybo Z7-20, Zedboard, or something different? Thanks, JColvin

    Arty voltage regulator failures

    Hi @jhauser-us, I am also concerned to hear this since I don't get to hear very often about that side of the business. Which particular Arty were you and your friend using (the original Arty or the Arty Z7-20) and do you happen to remember what revisions the boards were so that I can make sure from my end that the appropriate engineers are looking into this with the information they need? Additionally, is there anything unique about your power supply or is it a fairly standard 12V-3A supply with a center positive plug? What sort of designs were you working with, i.e. smaller designs with some basic I/O and logic, or some larger designs that used HDMI and other components that draw a lot more current? Thank you, JColvin
  6. Hi @Flux, Thank you for taking the time to share your project! Thanks, JColvin

    ZYNQ -7020 Development Board OOB code

    Hi @ArKay99, I'm not in the office to check this for certain, but offhand I would guess that the out of the box demo you downloaded from the Zybo Z7 Resource Center does not include all of the necessary materials in the .zip. I'll double check this and make sure it gets updated tomorrow. What you can try in the meantime is the HDMI demo project that is in the example projects above the additional resources section for another demo that doesn't require some additional hardware that you might not have ready access to. Thanks, JColvin

    Spectrum Analysis Problem

    Hi @nick hamilton, I have moved your question to a section of the Forum where the engineer much more familiar with the Analog Discovery 2 and the WaveForms software will be able to see and respond to your question. Thanks, JColvin
  9. Hi @Marty, The answer depends on how determined you are to use all of the predesignated SPI pins that are available on the WF32. Base on how the SPI library is implemented, you can use any number of GPIO pins without needing to directly implement them as part of the SPI library commands; you just need to raise and lower the CS logic level as appropriate. With that in mind, you can probably use upwards of 10 modules without any issues. The main two issues that you will run into will be the power requirements for running a lot of modules and the amount of data that you can receive within certain time frames; it looks like the conversion time for the module is about 100 ms. Let me know if you have any other questions about this. Thanks, JColvin
  10. Hi @Rich, Unfortunately, I don't think such a table exists for Digilent's microcontroller boards; part of the reason for this is because even if the microcontroller does not have a Pmod host port, you can still individually wire the pins from the Pmod to the microcontroller, utilizing either dedicated communication pins for the appropriate protocol (SPI, I2C, etc) or bit-banging out the appropriate protocol on a GPIO pin. In general though, all of our non-FPGA boards support all of our Pmods (with exception of perhaps the Pmod VGA which would require faster signaling than our microcontrollers can support). If you have a question on a particular combination of microcontroller/microprocessor board with a Pmod or if Digilent has a certain style (temperature sensor, motor driver, etc) of Pmod or a Pmod with certain specifications, I can more readily answer that. Thank you, JColvin

    Cmod S6 3D CAD data

    Hi @s.schwarzbauer, Unfortunately, we do not have a 3D model of the Cmod S6. I can try to get some of the dimensions that you would need for your model, though know that they would just be measurements that I personally took with calipers and not a more formal set of dimensions. Which dimensions are you looking for? Thanks, JColvin
  12. Hi @parvy, No, I don't think anyone at Digilent was aware of this since (I believe; I wasn't at Digilent at the time) we developed this board (Spartan 3A/3AN) for Xilinx, but from my understanding did not sell it ourselves. We also do not have the ability to update the source for the user guide as that was also created by Xilinx, but I'll be sure to direct future users to this bit of information as well. Thank you, JColvin

    Labview with arduino Mega

    Hi @mustafasei, To update the firmware on the board, go from the Tools tab at the top of the LabVIEW GUI -> MakerHub -> LINX -> LINX Firmware Wizard to load the appropriate firmware onto the Arduino Mega. Let me know if you have any questions about this. Thanks, JColvin

    Interface RGB display with Zynq 7000

    Hi @tekson, None of the Digilent employees have used either of those boards so we don't have any direct advice. It looks TI has a demo for using the DLP board with the Beaglebone boards. It may be good to reach out to TI to see if they have some recommendations on getting their mini projector working with a Xilinx SoC. Thanks, JColvin

    JTAG HS3 Under Device Manager - What is it?

    Hi @ArisBock, The JTAG HS3 will show up in the device manager as a USB Serial Converter with a Device Description as a "Digilent USB Device". You can also see if our Adept software sees the JTAG HS3 module. Let me know if you have any other questions. Thanks, JColvin
